Reduction of BOD/COD

Reverse Osmosis Polishers can concentrate BOD/COD from evaporator condensate and RO permeate streams to reduce waste water. Polished water can also be re-used in plant for boiler water make-up and CIP systems.

In Dairy Industry applications, "polishing" of these process water streams aids in the production of Class I water for re-use from dairy products as defined and regulated under Food & Drug Administration rules. Water produced with this technique is also very soft, generally resulting in lower cleaning chemical consumption.
